cool, but can you add a description of where the components are ( like the dynamos ). I think there were two, a main one and a backup one. The main one disabled during the final plunge (when the 7th compartment flooded)
There was also the telegraph. I have made a pdf showing the basic principle of the telegraph operated from the panel on the switch gears. As there is no wiring diagram to be found, I've made one after how I understand it described in "The Electrician" 1911.
